In March, we received an inquiry for overhead crane from Muhammad, who is looking for aircraft maintenance overhead crane for Akwa Ibom International Airport in Nigeria.

Akwa Ibom International Airport has now been renamed to Victor Attah International Airport,Akwa Ibom International airport has a constructed Maintenance, Repair and Overhaul facility capable of handling aircraft maintenance and overhaul of heavy commercial aircraft. The facility can conduct the A, B, C and D check. The facility, specifically designed for the Boeing 747, can accommodate two Boeing 747-400 parked juxtaposed, nose-in, fully contained within the building. The facility equipment, arrangement, clearance and supporting workshops allow flexibility for servicing a wide range of commercial aircraft.

10 ton Underslung Overhead Crane Quotation

According to Muhammad's detailed requirements, we quoted the price three times, namely the price of the crane, the price of the power supply system (4*150m busbar) and the price of 3*9 m I-beam. 4 sets of 10 ton underslung overhead crane and these accessories include the sea freight, the total amount reached 11.1 million US dollars.

In addition to email communication for important information, we also use WeChat to keep in touch with our customers. All questions from Muhammad can be answered in a timely and accurate manner, and the whole project went very smoothly.

Dear Muhammad
Good morning!
we received your payment today, firstly thanks for your trust and support!
in order to avoiding some misunderstandings in future there are some things need to confirmed and clarified with you.
check the final technical drawing, if everything is ok, we will start the production today.
find the enclosed I BEAM drawing pls, it is your current rail size for the crane, if so, we will produce the crane wheels according to this I BEAM you provided to us before.
regarding the proforma invoice, it includes crane value and sea freight both, it is workable for you to pay for the 50% of the crane value in advance, and then process the sea freight when delivery, but one point i need to clarify, the sea cost only including sea freight, no including the container price, when you received the goods, you have to return the container to shipping company, it is estimated to need 4pcs to load these 4 cranes.
waiting your confirmation, thanks so much!
Warm Regards    
Barley

According to the trade regulations of Yuantai Crane, production can only be arranged after receiving the customer's advance payment to avoid unnecessary troubles. At the beginning of July, after receiving Muhammad's advance payment, Barley made final confirmation on some key information and customers before production. This action has indeed played its due role, Muhammad confirmed that the thickness of the weld needs to be reduced from 25mm to 15mm. If there is no information confirmation, we will produce according to the incorrect size.

It took the production department more than a month to complete the production of these overhead cranes. Barley gave feedback on the production progress to the customer, and it can be packed and shipped after receiving the final payment. The lifting equipment we export to Nigeria usually requires SONCAP certification, and Muhammad also mentioned this to us. Therefore, we carried out the SONCAP certification before delivery and submitted it to the customer for use.

About the Crane Installation

Due to the COVID-19 pandemic, our engineers were unable to provide overseas installation services, so the entire project could only be installed by the customer’s team. The following are some installation reference files sent to customers.

In addition to these documents, we also have a series of installation videos for customers' reference. The installation of overhead cranes is relatively easy. Through documents, videos and remote assistance from our installation engineers, customers are fully capable of installing the cranes by themselves.

The Nigeria International Airport project went very smoothly. Customers know their own needs; we only need to quote and produce these customized overhead cranes according to the requirements.
